7 Reasons Why Dating Is Unfair For Young Women Today And You Had No Idea

Dating is a crazy numbers game.

Author Jon Birger just wrote a new book called "Date-onomics" which details the challenges that young college-educated women face when dating.

"Today's uneven gender ratios add up to sexual nirvana for heterosexual men, but for heterosexual women — especially those who put a high priority on getting married and having children in wedlock — they represent a demographic time bomb," Birger wrote in the Washington Post.

Here are seven ways that dating can be grossly unfair for today's women, and Birger says the problems originate in college:

2. Young men hold all of the cards.

The consequence of the college gender imbalance, Birger suggests, is that young men are in high demand and don't want to settle down. Thus, they control the dating game on their terms where romantic interactions become more sexually based. The result: Women could be more "sexually objectified."

5. Young women competing over a small number of guys.

As one female college student said to WND: "Out of that 40 percent male population, there are maybe 20 percent we would consider dating, and out of those 20 percent, 10 have girlfriends, so all the girls are fighting over that other 10 percent." Whether or not this is true, it certainly seems unideal.

6. The LGBT factor in certain cities.

In many LGBT-friendly cities, like New York, Miami and Washington, there are more gay men among the dating population. Jon Birger estimates that the result of this is a ratio of roughly three straight women for every two men, which is another factor working against the odds of women.

7. The best and worst cities for single women might surprise you.

One factor that women should consider is the number of employed single young men in each metro area. The best cities with a high ratio of these men include San Jose, Denver and San Diego. The worst cities with a low ratio of available men include Memphis, Jacksonville and Detroit.
